Well, what you waiting for?
Give us a laugh!

The new radiator came today. It is set up for reverse flow to accommodate the LFX.

Where did you order it from? Maker? Cores? Size? Depth? hp rating?
Does it sit in the lower pocket without modification or will you have to perform some BFH enhancements? (Edit: looks like the intake hose bung hits the pocket sheet metal...
Obviously you'll have to fab up some custom top and side mounts...
I'm not quite to this point yet, but it's coming very soon on the docket...[This message has been edited by msweldon (edited 08-08-2020).]

It is a Northern Radiator kit #209663B I found on Ebay. The seller is a shop in Minnesota, Dillon Radiator. They finished it to my specs and sent it to me. Below is the manufacturer's site with specs.

This is where my evap canister ended up. It originally fits several later models from GM including the Buick Verano and Chevy Cruz., and now a Pontiac Fiero with an LFX.

You probably want to grommet that hole in the upper frame rail.

Getting back to the radiator, what pressure cap should I use? The Impala donor car uses a 20 psi, but Fieros are significantly less than that. Any thoughts?

Modern cars use higher cooling system pressures to mitigate nucleating bubbles from micro-boiling events in the cylinder head cooling jackets. The cooling jackets in modern engines are pretty thin to promote quick warm up and require pretty high flow speed in order to carry enough heat away from the engine metal. Some micro-boiling is planned in, as the latent heat of vaporization does an excellent job of cooling. Lower system pressure will allow "more", but whether that's enough more to be more than the coolant flow can move out of the jacket and into the surge tank is a question you'll have to answer with practical experience.

Will, if I go with this cap on the reservoir, do I need a cap with a relief valve on the radiator, or do I get a solid cap?
